Lerette said they were also watching developments in the search of a Johnson County landfill. Lerette calls this a day where Irwin and Bradley, as well as other family members, are trying to get some sleep after a tension-filled week.

The couple's 10-month-old daughter, Lisa, disappeared from the parents' home in the 3600 block of North Lister Avenue between late Monday night and early Tuesday morning.

Bradley's grandfather offered an explanation for the police statement on Thursday that the parents were no longer cooperating with police, which is a claim the family disputes.

David Netz, Sr. said the couple simply objected to police-questioning tactics.

"They would come in and say, 'OK, Jeremy said this, and they'd go back to Jeremy and say Deb said this and that," Netz said. "When you're tired and worried about your baby, you're bound to make itty, bitty mistakes in time lines."
